Certain SFC emulation test cases that were given to byuu
"hdma" tests HDMA being started mid-frame, when other channels are active or inactive at the beginning of the frame (press B to switch)
it assembles with bass
"ayaya" tests mosaic in hi-res mode (press Y to toggle mosaic) (other buttons do other unrelated things)
i honestly forgot what "m6" tests (something offset-per-tile related obviously)
"ayaya" and "m6" assemble with asar
